Menus in QuickBASIC

Using MENU Resources in Microsoft QuickBASIC

Now that Microsoft has released QuickBASIC for the Macintosh it has become possible to access the entire Macintosh ROM using the ToolBox call. This article describes the use of these ToolBox calls to utilize MENU resources. This use is not described at all in the QuickBASIC manual, nor in any of the example programs that are supplied with QuickBASIC. I have supplied actual tested code, that will allow you to see how each of the routines are used, and will describe the pitfalls that await the user of these calls.

Warning!! This type of programming is not for the faint of heart, make any mistakes, and the best you can expect is that nothing happens. The more likely result of not following the rules that I describe later is an instant bomb, and the need for a manual reset using the programmer’s switch. You may be asking yourself at this point why should I go to all this trouble when QuickBASIC gives me the MENU functions to perform these operations already? My answer is no reason at all unless you want to follow the Macintosh interface guidelines, put icons in your menus, or access the full power of the Macintosh menu system.

Resource Rules

Before I describe the routines and how to use them let me state the rules of using these calls, and how to avoid problems. I will also describe some of the resources that I will discuss.

The following rules apply only if you are going to use your routines in the interpreter mode of QuickBASIC

1) Never use a MENU resource that has the same ID number as one of the QuickBASIC MENU resources, or the same MenuID as QuickBASIC. This means that the resource ID’s of your MENU resources should not be in the range 256-262 , and the number of the MenuID should not be in the range of 1-7. This last number is the one that is returned in the function MENU(0). The first number is the unique ID that is seen when you open up the MENU resource inside ResEdit.

2) Never use a DLOG resource that has the same ID number as one of the DLOG resources used by QuickBASIC. That means that dialog boxes that you use in your program should not have a resource ID number in the range 128-145. The reason for this is that if you need to perform a search and your DLOG resource has the same ID number as the search DLOG, your dialog box will be shown not the one that QuickBASIC uses for searching. As you can imagine this can cause all sorts of problems, and funny situations.

3) Always initialize any and all variables that you use in any ToolBox call. Failure to do so will result in many spectacular bombs. Because of this, and other reasons I suggest that you always save your program before you tell the interpreter to start running the program. If this program is a minor revision and you can keep the changes in your head, then go for it. I always manage somehow.

The following rules apply whether you are using the interpreter or a compiled version of your program.

1)The MENU(0) function will always return one less than the ResEdit MenuID. For example, in my example program, my file menu has a ResEDit MenuID of 10, but the QuickBASIC MENU(0) function returns an ID of 9. This is because QuickBASIC, starts numbering the menus from zero. The MENU(1) function returns the proper code, so no problem here.

2)Do Not remove the open and close braces which I have placed around many of the variables that are referenced in the various ToolBox functions. Without the braces the information is not passed properly, and so you will get nothing but garbage in your menus.

3)If you place these toolbox calls in subroutines be sure to use braces around the same information when you call the subroutine.

4) If you use ICON’s in you MENU resources remember they must be numbered in the range 256-512, and you access them as 1,2,.... 255 not by their resource ID. This basically means the number you feed to the ToolBox routines is the icon resource ID - 255.

5) Be sure to transfer the resources over using ResEdit when you compile the application. QuickBasic doesn’t do this for you except for a few resources.

6) Note the subroutines which I have provided to convert from BASIC variable to Pascal variable types the Macintosh ROMs require. These routines are necessary to convert the 4 character resource string that is used in BASIC to the 4 byte variable that is used by the Macintosh ROM. The other routines convert the style string that is customarily used in the resource compilers into an integer that is compatible with the Macintosh ROM and vice versa. Also note the intermittent use of the BASIC SADD function in order to send the address of a string variable to the ROM routine, in some cases using the SADD function is deadly. I have experimented with all these routines on a Mac Plus, Mac SE and a Mac II to make sure they work properly. The lesson is change them at your own risk.

The Calls

Those are the “rules” to follow, if you follow them diligently all will be well, if you don’t; good luck. Now for a description of the Calls and what they can be used for. In each of the QuickBASIC calls you must specify the type of return if any by using a single or double letter code. As you can see from the listing only four of the functions associated with Menus return a value, in most cases a handle to a menu, in the other case an integer number corresponding to the number of items in the menu. I have used a “Q” following each function in order to disable the argument checking function that is built into QuickBASIC. If you wish you may use the specially converted ResEdit that is supplied with the QuickBASIC to create argument checking functions for each of these calls.

With each of the functions I have provided a Trap value that is used to call the particular ROM routine, an example template of the ToolBox call, and the argument checking template that can be inputted using the QuickBASIC converted ResEdit. At this point I would like to thank Stephen Chernicoff the author of Macintosh Revealed, which I used extensively, and of course the authors and editors of Inside Macintosh.

The example program I have included starts off by reading the MENU resources from it’s own resource fork, and then sets up a processing loop to perform the various functions when the user selects an item from the function menu. I don’t perform any cut,copy paste so I just trap this function and print out the choice you made. The Graph Menu and File Menus show some of the reasons you may decide that using resource MENU’s instead of application built ones are more fun and just as easy to use.

By using the function provided in the Function Menu you can change any of the current menus,load another resource menu that you have created in ResEdit, or create a new menu and add items to it. This simple program does not allow you to save your work, although you could change the File Menu to include a save function and then use the WriteRes or AddRes functions that are described in the QuickBASIC manual.

The general procedure that I have implemented in using these functions in any of my QuickBASIC programs is as follows:

1) Create a BASIC program with a minimal amount of code to act as a holding place for the resources.

2) Use ResEDit to create the necessary resources in that QuickBASIC file. Remembering to write down the Resource ID numbers and other ID’s. For example, in the dialog boxes I use to prompt the user for information to feed the ToolBox calls, I must specifically reference each element by number.

3) Save my work when ResEdit asks me to save the work I have done.

4) Use the ToolBox functions instead of the BASIC Menu functions to change the state and look of the menus. If you try to use the QuickBASIC Menu function, to change any of the menus you have brought in as resources you will only cause problems for yourself. It’s OK to use the MENU(0) and MENU(1) functions to determine which menus the user has selected.
